Pre – grind

isi Germany ECOGUARD Pre-Grind is a water based concentrate, non-hazardous biodegradable cleaner and etching compound formulated for preparing concrete surfaces for easier grinding using higher grit metal diamonds on the first cut to obtain a quick and clean exposed Salt n’ Pepper surface, or a clean Cream polish finish using low grit resin diamond abrasives. ECOGUARD Pre-Grind is formulated using organic acids and surfactants made from naturally occurring materials, which makes it safer to use and just as effective as traditional hydrochloric or phosphoric based solutions.
